IMPROVEMENT IN WQOD-SAWING MACHINES.

Specification forming part of Letters Patent N0. 149,736, dated April14, 1874; application Sled March 11,1874.

To all whom t may concern: y

Be it known that I, JOHN L. Forman, of Coal City, in thecounty ofVenango and State ot' Pennsylvania, have invented a new and ImprovedVIood-Sawing` Machine; and I do hereview.

The invention relates to machines for sawin g wood; and consists in thefeatures of improvement hereinafter described, and subsequently pointedout in the claim.

A represents the frame on which. is supported the wood, and a a therecesses that receive it. Bis a sickleshaped clamp, having shank b andapertures b, the same turning,l on a cross-bolt, b2. C is a lever,pivoted at c, and connected with the clamp B by a strap, B', pivoted toeach.' D is a vertical ratchet-bar, in whose teeth the lever is heldwhen the clamp exerts pressure on the wood that is to be sawed. Logs orsticks of varying.;` size are thus readily and securely clamped and heldinposition. E is a frame, in which is suspended the saw F on the pivotedand slotted bars G H. To the former the end of saw-handle is jointed,while the said handle also rests loosely in a notch of and slides on thecross-bar h of the other. The bar H is pivoted to a lever, l, that isitself fulcrumed on the driveeshaft J, and provided with an adjustablecounterbalance-weight, K. L is a rod or bar attached laterally to theend of lever,and. held in the 'teeth ot' a ratchet, M. By this means thebar vH answers three several purposes-namely, to

support, guide, and lift the saw. The bar G is connected with the cranku ot' drive-shaft N bythe pitrnan O,Wl1ich is adjustable in one or moreholes, g, so as to regulate the throw of the saw according1 to the sizeof Wood which is to be operated upon.

Having thus described my invention, what I claim is The combination ofthe slotted bar G having` holes g, saw F, intermediate pitman 0, crank nwith its ope-rating mechanism, and drive-shaft N with the slotted bar H,having' notched cross-bar h at the bottom and pivoted to one end oflever I, drive-shaft J, lever 1 provided With counterbalance-weight K,rod L, ratchet-teeth M, pivoted sickle-shaped clamp B, strap B', andlever C, all constructed to operate substantially in the manner and forthe purpose set forth.
